Bayern Munich have extended the contracts of teenage midfielder Gianluca Gaudino and veteran goalkeeper Tom Starke, the club 12 points clear in the Bundesliga said on Wednesday.

The 18-year-old Gaudino, son of former Germany international Maurizio Gaudino, has signed a three-year extension until 2018, having made his debut in the opening league win over Wolfsburg last August.

The teenager came on for the last 20 minutes of last week's final group stage 3-0 win against CSKA Moscow to make his Champions League debut.

Reserve goalkeeper Starke, 33, has extended his stay until June 2016, but has yet to play a single minute of this season as Manuel Neuer's back-up.

Bayern play their final Bundesliga match of 2014 on Friday at Mainz before the winter break starts with their first game of next year on January 30 at Wolfsburg.

Swiss midfielder Xherdan Shaqiri and Denmark's Pierre-Emile Hojberg have both been linked to transfers having spent much of the season so far on the bench.
